How To Test A 24v Alternator. Faulty voltage regulators where applicable causing alternator output to increase with increasing engine speed. Fit a new high-quality belt over the appropriate pulleys.
Amps are determined by the load not the alternator. It leads to the alternator and connects to the terminal labeled B or Bat Place the sensor on the end of the red wire from the multimeter onto the metal alternator terminal. If you can find a way to isolate the regulator raise ground reference 12volts.
This is 146147 volts for a 12 volt nominal installation and 292294 volts in a 24 volt.
How do you test a 24 volt alternator. For 12v or 24v systems if this is less than 135 or 255 volts respectively when above 1500 RPM the alternator output is low. The rpm is less than 1500. Alternator or related faults that can cause the above symptoms are.
